I had my supposedly male ball (~1000g) out on the table with my other smaller known male ball (~300g) for a photoshoot. The smaller one started moving around the bigger one and I freaked out because I saw something red at the smaller one's vent and thought it was a prolapse or injury so I quickly picked him up. Turns out it was actually the hemipenes because he immediately retracted them again when I picked him up.
Was he actually trying to mate with the other one? Does that mean my other snake is actually a female? I obviously don't want to breed them at their current size.
